SPECIFICATION forming` part of Letters Patent No. 447,003, dated February 24, 1891. Application tiled March 18, 1889. Serial No. 303,653. (No model.)

To @ZZ wiz/0171, t may concern:

Be it known that I, JOHN H. McGowan, a citizen of the United States, residing at Oincinnati, Ohio, have invented new and useful Improvements inFinisher-Presses, of which the following is a specification. y

My invention relates to hydrostatic nisher-presses such as employed in plug-tobaeco manufactories, embodying, essentially, ahydraulic cylinder, usually placed at the bottom of a press-frame and operating a platen vertically in relation to a head-bar as an opposite abutment, and carrying a finisher in which is placed the substance to be compressed.

rlhe general construction and arrangement of iinisher-presses and their uses are fully described and illustrated by me in previous Letters Patent of the United States granted and issued to me April 6,1880,No. 226,334E and No. 226,335, and March 8, 1881, No. 238,493, based upon wh atare now known as double-end finisher-presses, and another patent granted and issued to me September 20, 1881, No. 247,385, relating' to improved construction and attachments of said presses. The finisher proper as used in such presses is a easin g havting one or more hinged doors opening laterally to remove or insert contents, and is necessarily made exceedingly strong and heavy to withstand the great pressure applied to the contents and prevent lateral expansion. The compression is effected by sinker-blocks of a size adapted to enter the open ends of the finisher, one of which blocks is placed upon the platen and the other suspended from the head-bar of the press-frame, the finisher being supported upon the side bars of the frame and held in place and centered by the sinker-bloelis, which proj eet slightly into the finisher when the ram or plunger is down. This renders it necessaryto open the easing to insert additional contents. Obviously the space occupied by the contents is reduced by the compression of the sinker-bloeks to a fraction of that iirst occupied, and it will be readily understood that in'opening the casing to insert additional contents a very slight residual elasticity in the compressed contents makes it extremely'diftlcult and in many eases impossible to reclose` the easing, so that praetically the capaeityiot' the press is limited to the one pressing at a time, which forms, for.

example, only a small portion of an ordinary butt or caddy of plug-tobacco.

My present invention, which is in the nature of an improvement upon my said former patented constructions, embodies a construction and arrangement of the finisher in its relation to the frame, platen, and sinker-blocks Whereby it is permanently but adjustably secured to the frame so as to be easily and quickly removable from the axialline of the ram and sinker-blocks into a position convenient ot access, and is as easily and quickly restored to its former position.

By the improvement a great saving of time and labor is attainedfin the ordinary manipulations ,of the press, its capacity for being additionally charged without opening the nisher laterally also adding to the general capacity of the press in a given time.

Other important advantages iiow incidentally from the improved construction. For example, the entire removal ofthe finisher from the axis of the ram enables the ram to be lifted out for repairs, packing, tbc., or any other repairs to be made without the delay or extra labor heretofore caused by having Iirst to remove the finisher bodily from the press. It also facilitates the unloading of the finisher by its being swung into a position where the butt or caddy can be placed directly beneath in position to receive the entire contents ready for packing.

Mechanism embodying my invention is illustrated in the accompanying drawings, in which- Figure 1 is a front elevation ot my improved finisher-press, showing the inisher pivotally supported upon and in relation to the pressframe; Fig. 2, a side elevation of the press complete; Fig. 8, a plan or upper end view ot the linisher and attachments sectioned through the press-frame in the plane oc of Fig. 1; Fig. a, a plan or upper end view of the cylinder sectioned on the line y ly of Fig. 1; Fig. 5, a detail plan showing more fully the construction and arrangement of the operatinglever, gage-shelf, and guide-stop; Fig. 6, a vertical section of the press complete, taken through the vertical center line et Fig. 1; Fig.

T. a detail of supportingshelt' and gage-plate. showing more clearly their relation one to the other.

Referring now to the drawings, A designates the cylinder; :3, the rain or plunger; C, the platen; I) D, the side stanehions or standards supporting the head-brace or press-bar E in the usual type of tinisher-press, and F the finisher proper, consisting' of a stout easing, usually of cylindrical exterior and rectangular interior section, one segment being pivotally secured to the remaining portion and adapted to open apart; for charging or discharging the contents.

In practice the sinker-bloel s a a-one carried upon the platen C and the other at the under side of the press-bar lil-arc by the elevation of the platen and finisher against the press-bar forced into the upperand lower openings of the finisher, compressing the contents between their corresponding surfaces and the inner walls of the finisher.

In former constructions the finisher rested upon supporting-lugs attached to the side bars of the press, was held centered by the constant projection ofthe sinker-blocl s above and beneath slightly into the open ends of the finisher, and in order to add to the charge after compression it was necessary to open the finisher laterally. ',lhis, as will be readily seen, involves delay and extra labor, and was attended with great difficulty and uncertainty n reclosing the finisher, owing to the residual elasticityof the compressed contents and consequent expansion upon opening. For this reason the reelosing always brought great strain and destructive wear upon the screw-threads and pintles of the fasteningbolts, and, in fact, it was practically impossible in most cases to insert additional charges in this manner, so that as a practical result only a small portion of the caddy or butt of tobacco could be pressed at a time, and this must be entirely removed before recharging the finisher. To obviate these difficulties I suspend the linishcr I? by a pivotal connection at one side ot the press-frame, by which it may be swung ont of the way ot' the platen and sinker-blocks and recharged without loss of time or difficulty. In the preferred construction here illustrated I accomplish this by pivotally mounting the finisher-casing by means of loops b Z), embracing a vertical cylindrical bar c, secured in and between a lng or projection d upon the pressbar, and a corresponding lng or sock et-piece e, secured to the adjacent standard I). The pintle-bar c remains permanently in position; but the sliding tit of the loops h h upon the bar c allows the fmisher to be carried up or down,as impelled by the movements of the ram and platen, and perfectly guided at all times.

The details of the construction here shown have been somewhat controlled by existing conditions of the manufacture; but the essential principle of myinvention maybe carried out in various other methods of construction.

` cylindrical and employed for .is these presses are usually built with reet:- angnlat-sectioned side standards l), l prel'er to malte the lower holding-lug col the pintlebar an adjustable attaclnnent upon said bare. As shown in Fig. Ii, it consists of a plate or cap c', cast with a perforated extension for the reception ol' the pintle-bar e, and fitting the standard I) attwo sides, and a corresponding plate or cap c2 fitting the standard at the remaining two sides. '.lhe two plates or caps are bolted together, clan'iping and embracing the standard to form the lng e, supporting the entire weightot` the finisher F when swung out of the press-frame. The clamp thus formed fits two of the sides of the standard I) closely; but in the general crossplanc of the press-t`rame a space for adjustment is provided, and a set-screw s is inserted through the cap e2, bearing against the standard l). ly manipulating this set-screw the true vertical alignment ofthe axis of the tinisher with that of the ram and sinkcr-blocks is always preserved or readjusted when lost through wear or lost motion in the pintle connections. The general construction also af' fords a convenient means of adjustmentvertically to take up lost motion due to wear, the.

To the opposite standard I), near the upper endet the tinisher, I attach asapporti11g-shelf j", also adjustably secured by bolts to the press-bar. It is operative in connection with the corresponding gageqjilate g, attached to and projecting from the iinisher in proper relations to the shelff, as a means of determining and correcting the alignment of the linisher with reference t-o the sinlicr-ljilocks. To facilitate the proper engagement of the shelf and plate, their corresponding surfaces are slightly beveled at the engaging edges.

rlhe gage-plate g is cast with a lever-socket h projecting angnlarly above and at one side, anda guide-stop arranged to impinge against the press-stamlard D. The lever-socket is for the reception of a handle or bar h for the rotation of the finisher upon its pintle connec tion, and the stop if limits said rotation by coming in contact with the standard D as an abutment. 'lhus a means of bringing the finisher into exact relations with the ram and sinker-blocks is provided, requiring nc skill to operate.

It will be seen that by proper vertical adjnstment ot' the shelff in relation to the plate g the weight of the finisher and contents is divided between the lng c and the shelf j when the parts are in closed position andthe friction of the plate serves to hold the parts in position.

It will be obvious that instead of employing a separate bar ein addition to the two guidebars Il) as a pintle upon which the finisher is swung, one of the guide-hars D may be made this purpose; but the construction shown is preferable as one available in common for existing presses and for new ones constructed according to my present improvement.

The finisher isnormally held at a height to clear the lower sinker-block ct when swung out, and for the same reason the upper sinkerblock is gaged at a proper height to clear the finisher.

My invention is not necessarily confined to tobacco-presses, but may be applied to all presses where similar conditions exist.

I claim as my invention and desire to sccure by ALetters .Patent of the United Statesi. In a hydraulic press, the combination of the press-frame, a sinker-block attached to the head-bar of the frame, a finisher-casing open at both ends and pivotally secured in parallel relations with and movable vertically in the axis of the ram, and a ram extended into a platen and arranged to elevate the tinisher around the u psper sinker-block, substantially as set forth.

2. In a hydraulic press, the combination of the press-frame and operative parts, an openended finisher pivotally secured in parallel relations with and free to move vertically in the general axis of the ram movement, and an adjustable stop for supporting the finisher at its lower limit of movement, substantially asset forth.

In a press of the character described, a vertically-pivoted iinisher swinging into and out of the general axis of the press movement, an adjustable supporting-*shelf upon the press-frame in the horizontal path of the iinisher, and a gage-plate on the finisher engaging said adjustable su pporting-shelf to guide and hold the finisher' in proper position axially in relation to the sinker-blocks, substantially as set forth.

4. In a finisher-press, in combination with the ram, press-frame, and sinker-block, afinisher provided with side loops, a fixed pintle embraced by said loops, upon and by which the finisher is held and permitted to swing horizontally and permitted to be moved and guided vertically as lifted by the platen, substantially as set forth.

5. In a finisher-press of t-he character described, in combination with the presserframe, the pintle-bar and the finisher carried pivotally7 thereon, the supporting` lug e, clamped adj ustably to the side bar and forming a holding-socket for the pintle-bar, and an adjustable bearing for the finisher, substantially as set forth.

6. In a finisher-press of the character described, in combination with the press-frame, pintle bar and nsher carried pivotally thereon, a gage-plate carried upon the finisher, and a corresponding supporting shelf or plate adjustably secured to the standard, substantiallyas and for the purpose set forth.

'7. The combination, in a finisher-press ot' the character described, of the finisher' pivotally hung to swing into and out of the axis of press movement, a guide-stop upon the finisher, and the opposite standard against which said guide-stop impinges to limit its swinging movement and retain the same in proper axial relations with the sinker-block and ram and align the inisher with the sinker-block, substantially as set forth.

In testimony whereof I have hereunto set my hand in the presence ot' two subscribing witnesses.
